C# alternatives to #if #endif for attributes

Question

5.00/5 (1 vote)

See more:

In the last couple of MVC applications that I have made, each Controller action is preceded by this little snippet of code:

C#

[HttpGet] // or [HttpPost]
#if (DEBUG == false)
  [RequireHttps]
#endif
public ActionResult Index()
{
  // do something
}

I do this so that ISS Express can load up the website without any special HTTPS processing but I want the whole site to require HTTPS once past the login screen once it's loaded to the production server.

What I would like to know is if there is an alternative to using #if...#endif conditional compilation to add in attributes only for Release builds.

What I have tried:

I searched but I haven't been able to find any decent alternatives other than writing a whole class to wrap the Controller class. Conditional attributes look promising but I am not seeing how they could be applied to this situation.

I believe that those lines are there because the developer won't be bothered to set up a 'Self Signed Certificate' in the local IIS...
It is easy and very advised if you are writing an HTTPS-only site anyway...

[EDIT]
And set HTTPS on site level using (on application start):

C#

GlobalFilters.Filters.Add(new RequireHttpsAttribute());

You can create self-signed certificates for ISSExpress!? You learn something new every day. I assumed something as bare-bones as IISExpress wouldn't have that capability. Do you have a link to the steps?

While you did provide a viable work-around, the original question still remains unanswered and I am still curious if precompiler directives can be replaced in C#.

I think this will help you to configure IISExpress: https://www.hanselman.com/blog/WorkingWithSSLAtDevelopmentTimeIsEasierWithIISExpress.aspx (but I would say - use IIS even for development)...
As for #if #endif - I do not know any other structure to replace it, but in your case you can move it to application start (put Filters.Add in condition) and leave actions clear of that...
